[PATCH 13/20] parse-options-cb.c: convert uses of 40 to GIT_SHA1_HEXSZ

[Ævar Arnfjörð Bjarmason]

In ac53fe8601 ("sha1_name: convert uses of 40 to GIT_SHA1_HEXSZ",
2017-07-13) the code this is validating user input for in
find_unique_abbrev_r() was converted to GIT_SHA1_HEXSZ, but the
corresponding validation codepath wasn't change. Let's do that.
